Suppose a body is moving in circles.

Two things can be possible:

1. Either it is moving in circles with a continuous speed.

2. It is moving with an increasing or decreasing speed.

In the first case, the direction is changing, but the speed is not. In the second case, both, the speed is changing as well as the direction is changing.

Note: In both cases, direction is changing so Velocity is changing anyways as Velocity is a vector quantity.

hope it helps

Have a good day ahead ☺☺❤❤

Answer 2

Answer:

An example of the direction of motion changes with speed remaining constant and both direction and speed change simultaneously are Continuously spinning the stone that is attached to the string's end and the direction that a stone travelled after being tossed into the air, respectively.

Explanation:

• Continuously spinning the stone that is attached to the string's end is one of example direction of motion with changing motion but speed remaining constant. Although the motion in this instance changes direction, the speed doesn't. The motion of the moon around the earth is also an example of such a case.
• The direction that a stone travels after being tossed into the air is an example where the direction and speed both change simultaneously. Here, the motion's speed and direction both shift at the same time.

Thus, the example for the direction of motion changes with speed remaining constant and both direction and speed change simultaneously are continuously spinning the stone that is attached to the string's end and the direction that a stone travelled after being tossed into the air, respectively.
